The following reaction is at equilibrium in a sealed container.

Chemistry

Answer:

D.Lowering the temperature is the best option.

Explanation:

The value of equilibrium constants aren't changed with change in the pressure or concentrations of reactants and products in equilibrium. The only thing that changes the value of equilibrium constant is a change of temperature.

In the reaction below for example;

A + B <==>C+D

If you have moved the position of the equilibrium to the right (and so increased the amount of C and D), why hasn't the equilibrium constant increased?

Let's assume that the equilibrium constant mustn't change if you decrease the concentration of C - because equilibrium constants are constant at constant temperature. Why does the position of equilibrium move as it does?

If you decrease the concentration or pressure of C, the top of the Kc expression gets smaller. That would change the value of Kc. In order for that not to happen, the concentrations of C and D will have to increase again, and those of A and B must decrease. That happens until a new balance is reached when the value of the equilibrium constant expression reverts to what it was before.

What is the [H3O+] if the [OH-] is 1 x 10 -8?
Tanzania [10]

From the calculation, the concentration of the oxonium ions is 1 * 10^-6 M

<h3>What is concentration?</h3>

The term concentration refers to the amount of substances present in the solution. There are several units that can be used to show the concertation of a substances such as moles/liter, gram per liter, parts per billion, parts per billion, percentage etc.

Now we know that water is composed of the hydrogen and the hydroxide ions and the product of the both is generally known as the ion product of water and have a value of 1 * 10^-14.

If that be the case, we are in order to write the expression;

[H3O+]  [OH-] = 1 * 10^-14

[H3O+] = 1 * 10^-14/ [OH-]

[H3O+] = 1 * 10^-14/ 1 x 10^ -8

[H3O+] = 1 * 10^-6 M

An 8-year-old child fell to the ground from an 8-foot-high playground structure. He is lying on his back and moving very little.
Mariana [72]

Answer:

Pulse

Explanation:

The sign that would make me call 911 is his pulse. If the child's pulse is unresponsive, then that would be a clear sign for me to call the paramedics.

What is the correct definition of energy?
scoray [572]

Answer:

The ability to do work

Explanation:

  • Energy refers to the ability to carry out work.
  • It is measured in Joules (J).
  • Energy may exist in different forms such as potential energy when a body is at rest, kinetic energy when the body is in motion, etc.
  • Energy can neither be created nor destroyed, however, it can be transformed from one form to another. For example, chemical energy may be transformed into mechanical energy or other forms of energy.

Please help urgent Balance the following word equation:
LekaFEV [45]

Answer:

AlCl3 + 3Na > Al + 3NaCl

Explanation:

AlCl3+Na → Al + NaCl

Al =1 Al=1

Cl =3 Cl = 1

Na=1. Na = 1

so balance

and it would be

Alcl3 + 3Na → Al + 3NaCl

Which group of factors are most important in determining the composition of ocean water? a.)temperature, salinity, and density b
Elis [28]

Temperature, salinity, and density are the group of factors are most important in determining the composition of ocean water.

a.)temperature, salinity, and density

<u>Explanation:</u>

The three fundamental factors that help in determining the composition of ocean water are temperature, salinity, and density. Temperature, saltiness, salinity, and density influence the thickness of seawater.

Enormous water masses of various densities are significant in the layering of the sea water (increasingly thick water sinks). As temperature builds water turns out to be less thick. As saltiness builds water gets denser. The temperature helps in deciding the pace of vanishing of the ocean.
